摘要/Abstract

摘要： 为提高防空火箭弹激光近炸引信对来袭蜂群无人机的探测概率，采用空间解析几何方法描述防空火箭弹与来袭蜂群无人机的交会模型，提出一种防空火箭弹四象限周视激光近炸引信探测来袭蜂群无人机的方案。建立基于蒙特卡洛法的弹目交会探测概率模型，分析不同火箭弹转速、目标速度、激光脉冲频率与探测半径下的引信系统探测概率。计算结果表明：激光脉冲频率55 kHz，火箭弹转速40 r/s时引信系统有效探测到8 m内目标概率为0.788 8；引信系统探测概率的蒙特卡洛计算模型可为防空火箭弹四象限周视激光引信系统设计提供理论参考。

Abstract: The rendezvous model of the anti-aircraft rocket projectile and the incoming swarm unmanned aerial vehicle (UAV) is described by using the method of spatial analytic geometry. A scheme of a four-quadrant circumferential laser fuze for anti-aircraft rocket projectiles is proposed to detect the incoming swarm UAV, and a detection probability model of projectile-target rendezvous based on Monte Carlo method is established to improve the detection probability of laser proximity fuze of anti-aircraft rocket projectile for the incoming swarm of UAV. The detection probability of the system under the conditions of different rocket projectile and target speeds，laser pulse frequency and detection radius is analyzed.The calculated results show that the probability of the system effectively detecting a target within 8 m is 0.788 8 when the laser pulse frequency is 55 kHz and the rocket projectile rotation speed is 40 r/s.The Monte Carlo calculation model of the system detection probability can provide the theoretical reference for the design of four-quadrant circumferential laser fuze system of air defense rocket projectile.
